Email Signature Generator for Gmail — ProSignature

Your email signature, in every Gmail you write — without copy-paste. Design a professional email signature at prosignature.co: your logo, photo, job title, phone, website and social links, in one of 13 templates. Then install this extension. Your signature appears in each new Gmail compose window automatically, and it stays in sync when you change the design. HOW IT WORKS 1. Build your signature at prosignature.co. The free plan needs no credit card. 2. Open the editor once. The extension picks the signature up on its own. 3. Compose in Gmail. Your signature is already there. NO GOOGLE PERMISSION REQUIRED Out of the box this extension asks for no Google access at all. The signature is inserted locally, in your browser. Nothing is uploaded, and the extension never reads your mail. If you would rather store the signature inside Gmail itself — so it also applies on your phone — the site offers an optional path that asks for one Google permission for managing Gmail settings ("See, edit, create, or change your email settings and filters in Gmail"). It is used to write your signature into Gmail's settings, and it does not include access to the content of your messages. It is entirely optional and the extension works fully without it. A SMALL CREDIT LINE ON THE FREE PLAN Signatures made on the free plan end with one small line, "Created with ProSignature", linking back to the site. Pro removes it. Everything else in the signature — name, logo, links, banner — is yours. ALSO WORKS OUTSIDE GMAIL For Outlook, Microsoft 365 and Apple Mail on Mac and iOS, the site gives you a one-click copy that preserves inline-styled HTML — the format those clients keep — along with step-by-step instructions for each one. WHAT YOU CAN PUT IN IT Company logo and profile photo, job title and department, phone and mobile, website and address, LinkedIn / X / Instagram / Facebook / YouTube, a call-to-action button, a promotional banner, a sign-off line, and a legal disclaimer. FOR TEAMS Design one signature, lock the branding, and roll it out to everyone from a central back office, so every employee's email looks the same. PRIVACY The extension runs only on Gmail, inserts your signature locally, and does not read, collect or transmit the contents of your email.
